I just tried to reinstall PCLinuxOS2010. I made this CD last year and installed with no difficulties. The Live CD works fine and everything installs, I run the update as instructed on this web site. After the update completes, a DOS prompt comes up asking for host name and password. If I reboot in normal mode, the "Bull" logo appears but nothing else, if I boot in "safe mode" a series of DOS commands scroll and at the end is: No Inittab Found
Your ISO is too old to update. Get a fresh ISO from the download page.
